74ALS573B 74ALS574A Octal traparent latch (3-State) Octal flip-flop (3-State) FATURS 74ALS573B is broadside pinout version of 74ALS373 74ALS574A is broadside pinout version of 74ALS374 Inputs and outputs on opposite side of package allow easy interface to microprocessors Useful as an input or output port for microprocessors 3-State outputs for bus interfacing Common output enable 74ALS563A and 74ALS564A are inverting version of 74ALS573B and 74ALS574A respectively SCRIPTION The 74ALS573B is an octal traparent latch coupled to eight 3-State output devices. The two sectio of the device are controlled independently by enable () and output enable (O) control gates. The 74ALS573B is functionally identical to the 74ALS373 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. The data on the inputs is traferred to the latch outputs when the enable () input is High. The latch remai traparent to the data input while is High, and stores the data that is present one setup time before the High-to-Low enable traition. The 74ALS574A is functionally identical to the 74ALS374 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. It is an 8-bit edge triggered register coupled to eight 3-State output buffers. The two sectio of the device are controlled independently by clock (CP) and output enable (O) control gates. The register is fully edge triggered. The state of the input, one setup time before the Low-to-High clock traition is traferred to the corresponding flip-flop s output. The active-low output enable (O) controls all eight 3-State buffers independent of the latch operation. When O is Low, latched or traparent data appears at the output. When O is High, the outputs are in high impedance off state, which mea they will neither drive nor load the bus.
